摘要

The purpose of this paper is to develop a methodology that combines video images and digital maps for intelligent transportation systems (ITS) and geographic information systems (GIS). In this study, (1) the database structure of a digital map for integrating video images, (2) the georeferencing method of moving images by the time-tag; and (3) the hypermap data- base using Differential Global Positioning System (DGPS), were developed. The database was designed to replay a video image corresponding to a point on a two-dimensional digital map. Furthermore, the linkage of various objects existing both in video image and digital map was accomplished in this methodology. The practical use of hypermap research was examined by applying it to the proposed moving image georeferencing method. Furthermore, the level of accuracy was evaluated by utilizing the exact location of street lamps as control points, with the result that 92.8/100 of control points were included within two consequent frames.
